…but not quite. Here it is anyway, describing the database exchange standards between the FBI’s IAFIS, NCIC, NGI, N-DEx; the Department of Defense’s ABIS and NGA; and the Department of Homeland Security’s IDENT.

Two or three things I know for sure: it’s from 2008, has a good color scheme, and is intended to be read by people who understand phrases like “the NGI, N-DEx and NGA are NIEM-compliant” and “Based on the GJXDM, NIEM is an updated standard that…includes GJXDM as well as other data structures.”
